Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular, it is a lifting and fixing device for hoisting. Background Technology

[0002] In factories, hospital sterilization supply centers, operating rooms, laboratories, and other places, many pieces of equipment need to be installed on suspended ceilings. Currently, flange hoisting is commonly used. Flanges are generally used for connecting pipes to other pipes. Because the outer walls of flange-hoisted pipes are smooth, they usually require fixing devices to secure them to the flange. Since the flange needs to bear the entire weight of the pipe and its underlying components, the requirements for the fixing devices are very high; the pipe must be firmly secured to the underside of the flange.

[0003] In patent CN109276392B, a clamping ring is installed on the lower side of the flange to strengthen the fixation. However, with this structure, when the flange is hoisting the pipe fitting, it needs to bear the weight of the pipe fitting and the lower device, as well as the weight of the clamping ring. The bolts fixing the pipe fitting and the flange need to withstand a large tensile force. The bolts have high diameter specifications and are numerous, making the structure complex, cumbersome to install, and costly. If the hoisting bolts strip, there is also a risk of hoisting failure and equipment falling. In addition, since the clamping ring is located on the lower side of the flange, the pipe fitting is connected to the clamping ring, and the clamping ring is connected to the flange. There is no direct connection between the flange and the pipe fitting, so an expansion opening is required. The two sides of the expansion opening have outward protruding lugs with through clamping bolt holes. The clamping bolts make the clamping ring grip the pipe fitting more tightly, so as to ensure the rigidity of the overall connection. However, the addition of lugs further brings problems such as cumbersome installation and high cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a lifting and fixing device for hoisting that is simple in structure and easy to install.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: the hoisting lifting type fixing device includes a first connecting member, a fixing device and a second connecting member. The fixing device is set at the end of the second connecting member. The first connecting member is provided with a through hole for the second connecting member to pass through. The second connecting member passes through the first connecting member. The first connecting member is engaged on the lower side of the fixing device and connected to the fixing device.

[0006] Preferably, the fixing device includes two semi-circular clamps, each clamp having multiple protrusions along its circumference, the protrusions being parallel to the axial direction of the clamps, and each protrusion having a clamp threaded hole for connection with the first connecting member.

[0007] Preferably, the first connecting member includes a flange, which is disposed on the lower side of the clamp and is fixedly connected to the clamp by bolts disposed in the threaded hole of the clamp.

[0008] Preferably, the second connector includes a hanging column, a clamp is disposed at the end of the hanging column, the outer surface of the clamp is provided with a plurality of clamp connection holes parallel to the radial direction of the clamp, and the hanging column and the clamp are fixedly connected by bolts disposed in the clamp connection holes.

[0009] Compared with the prior art, the beneficial effects of this technical solution are as follows: By setting the fixing device at the end of the second connector, and providing a through hole for the second connector to pass through the first connector, the second connector passes through the first connector and is engaged with the lower side of the fixing device. When hoisting the second connector, the first connector supports the fixing device, and the second connector passes through the first connector, so the first connector restricts the coaxiality of the second connector. There is no need to set a clamping structure on the fixing device. The structure of this utility model is simple, easy to install, and has low manufacturing cost. Attached Figure Description

[0014] Reference Figures 1-2 The hoisting and lifting type fixing device includes a first connector, a fixing device, and a second connector. The fixing device is located at the end of the first connector. The second connector has a through hole for the first connector to pass through. The first connector passes through the second connector. The second connector is engaged with the lower side of the fixing device and connected to the fixing device.

[0015] Specifically, the fixing device of this utility model includes two semi-circular clamps 2, the first connecting member is a flange 1, the second connecting member is a hanging column 3, the clamp 2 is provided with four bosses 203 along the circumference, the bosses 203 are set in a direction parallel to the axial direction of the clamp 2, and the bosses 203 are provided with clamp thread holes 201 that are connected to the flange 1.

[0016] A through hole 101 is provided at the center of the flange 1. Four flange fixing holes 102 are evenly distributed along the circumference on the surface of the flange 1. Bolts pass through the clamp thread hole 201 and the flange fixing hole 102 to fix the flange 1 to the underside of the clamp 2.

[0017] At the end of the lifting column 3, four threaded holes 301 are evenly distributed. The outer surface of the clamp 2 is provided with four clamp connection holes 202 that are radially parallel to the clamp 2. After the lifting column 3 passes through the flange 1, the bolt passes through the clamp connection hole 202 and the threaded hole 301 of the lifting column to fix the clamp 2 to the end of the lifting column 3.

[0018] Installation process: Place flange 1 on column 3, fix two clamps 2 to column 3 with bolts, and finally fix flange 1 and clamps 2 with bolts.

[0019] The clamp 2 of this utility model is set on the upper side of the flange 1. When the flange 1 is used to lift the lifting column 3, the flange 1 supports the clamp 2. Furthermore, the flange 1 is fitted on the lifting column 3, and the flange 1 restricts the lifting column 3 and the flange 1 to keep coaxial. There is no need to set expansion openings or other clamping structures, and the structure is simple.
